Unit Status and DL/UL Status LEDs
The Expansion Hub unit status and DL/UL status LEDs can be in one of the states
shown in Table 4-1. These LEDs can be:
steady green
steady red
There is no off state when the unit’s power is on.
Table 4-1 Expansion Hub Unit Status and DL/UL Status LED States
LED State Indicates
Green / Green
Green / Green
• The Expansion Hub is connected to power and all power supplies are
operating.
• The Expansion Hub is not reporting a fault or lockout condition; but
the system test may need to be performed or a warning condition
could exist (use AdminManager to determine this).
• Optical power in is above minimum (the Main Hub is connected)
although the cable optical loss may be greater than recommended
maximum.
• Optical power out (uplink laser) is normal and communications with
the Main Hub are normal.
Green / Green
Red / Green
• Optical power in is above minimum (the Main Hub is connected)
although the cable optical loss may be greater than recommended
maximum.
• Optical power out (uplink laser) is normal and communications with
the Main Hub are normal.
• The Expansion Hub is reporting a fault or commanded lockout.
Green / Red
Red / Green
• A fault condition was detected, optical power in is below minimum.
(the Main Hub is not connected, is not powered, or the Main Hub’s
downlink laser has failed, or the downlink fiber is disconnected or
damaged.)
Green / Green
Red / Red
• The Expansion Hub is reporting a fault condition.
• Optical power in is above minimum (Main Hub is connected)
although the cable optical loss may be greater than recommended
maximum.
• Optical power out is below minimum (Expansion Hub uplink laser
has failed; unable to communicate with Main Hub).
UL STATUS LED
state must be checked within the first 90 seconds after power on. If
initially green, then red after 90 seconds, it means that there is no
communication with the Main Hub. If red on power up, replace the
Expansion Hub.
